Police arrested Reeves’ fellow airman, 24-year-old James Thomas and named him a person of interest. He’s facing six charges of tampering with evidence. He made his first court appearance on the tampering charges on Wednesday.

Thomas initially told detectives he last spoke to Reeves the day he disappeared via text message, and Reeves told him he was sick and receiving medical treatment. Detectives analyzed Reeves’ cell phone and learned the Reeves’ phone was in the area of Thomas’ residence the night of April 19, which was inconsistent with Thomas’s initial statement to law enforcement.

They secured a search warrant and during the search, found evidence of a violent crime inside Thomas’ residence. Investigators say Thomas told them when he came home, Reeves was at his place with an unknown individual.

Two days later investigators say Thomas changed his story, saying he came home and found a third person in his home holding a gun to Reeves. He says both men left the house after Thomas was held at gunpoint. Police say there was bloody clothing in the home, which Thomas took to a different residence, cut up and burned in the fireplace. They say he also removed a bloodied loveseat from his home and moved Reeves’ vehicle to another location.
